FAMILY LAMPADIOTEUTHIDAE BERRY, 1914

(ONE SPECIES)

Diagnosis: Small adult-sized and colourful Enoploteuthoidea with four ocular and five tentacular photophores (the most proximal stalked near the base of the tentacle), plus anal, branchial and posteroabdominal photophores, branchial photophores transversally elongated, without central abdominal photophore; rostrum in gladius; without hooks on arms and tentacles; right ventral arm hectocotylized with enlarged protective membrane in the mid-arm; males with single terminal organ.

Remarks: This group has a complex taxonomic history (see Vecchione & Young, 2019a). Berry (1914) erected this monotypic family, but it was later included as the subfamily Lampadioteuthinae Berry, 1914 within Lycoteuthidae by Naef (1923). Voss (1956) maintained them as separated families in an initial article. He then considered them to occur within the same family in a subsequent article (Voss, 1962). The results provided here support a familylevel treatment.
